Abstract: PURPOSE: A focus jump method of multi-layer disk driver is provided to perform precise focusing of a laser beam from a layer to another layer move by an application of a feedback control concept. CONSTITUTION: A focus jump method of multi-layer disk driver includes following units. When an object lens is decelerated normally, the gradient of a focus error signal become a negative number. If the movement of the object lens is reversed, since the gradient of a focus error signal is change into a negative number, as a result, the movement of the lens can grasp through an examination of the gradient of a focus error signal. At the moment that the movement of the object lens is reversed, since the moving speed of the lens is nearly 0, there is no a problem to start the focus control although the focus error signal has a comparatively large value. The values of PC_START and PC_END for determining the start and deceleration of the position control process may be fixed and preferably may be controlled according to the kinds of disks.
